ICMP Locator Update Message for the
Identifier-Locator Network Protocol for IPv4 (ILNPv4)
Abstract
This note defines an experimental ICMP message type for IPv4 used
with the Identifier-Locator Network Protocol (ILNP). ILNP is an
experimental, evolutionary enhancement to IP. The ICMP message
defined herein is used to dynamically update Identifier/Locator
bindings for an existing ILNP session. This is a product of the IRTF
Routing Research Group.
Status of This Memo
This document is not an Internet Standards Track specification; it is
published for examination, experimental implementation, and
evaluation.
This document defines an Experimental Protocol for the Internet
community. This document is a product of the Internet Research Task
Force (IRTF). The IRTF publishes the results of Internet-related
research and development activities. These results might not be
suitable for deployment. This RFC represents the individual
opinion(s) of one or more members of the Routing Research Group of
the Internet Research Task Force (IRTF). Documents approved for
publication by the IRSG are not a candidate for any level of Internet
Standard; see Section 2 of RFC 5741.

1. Introduction
This document is part of the ILNP document set, which has had
extensive review within the IRTF Routing RG. ILNP is one of the
recommendations made by the RG Chairs. Separately, various refereed
research papers on ILNP have also been published during this decade.
So the ideas contained herein have had much broader review than the
IRTF Routing RG. The views in this document were considered
controversial by the Routing RG, but the RG reached a consensus that
the document still should be published. The Routing RG has had
remarkably little consensus on anything, so virtually all Routing RG
outputs are considered controversial.

At present, the Internet research and development community is
exploring various approaches to evolving the Internet Architecture to
solve a variety of issues including, but not limited to, scalability
of inter-domain routing [RFC4984]. A wide range of other issues
(e.g., site multihoming, node multihoming, site/subnet mobility, node
